Cementing is arguably the most important operation performed on a well. Well cementing technology is an amalgam of many interdependent scientific and engineering disciplines which are essential to achieve the primary goal of well cementing - zonal isolation. This textbook is a comprehensive and up-to-date reference concerning the application of these disciplines to cementing a well.``Well Cementing'' is envisioned as an upper-level university book, as well as a reference for practicing engineers and scientists. The first section of the book illustrates how the quality of the hydraulic seal provided by the cement sheath can affect well performance. The second section concentrates on the design phase of a cementing treatment, and various aspects of cement job execution are covered in the third section. The fourth section addresses cement job evaluation. The text is supported by many tables and figures, an extensive bibliography and an index. There are also chapters devoted to subjects which are currently of particular interest to the industry, including the prevention of annular gas migration, foamed cements, and cementing horizontal wellbores. The chemistry associated with well cementing is presented in detail.Most of the contributors to this volume are employees of Dowell Schlumberger, one of the leading companies in this field.

Applied Well Cementing Engineering delivers the latest technologies, case studies, and procedures to identify the challenges, understand the framework, and implement the solutions for today’s cementing and petroleum engineers. Covering the basics and advances, this contributed reference gives the complete design, flow and job execution in a structured process. Authors, collectively, bring together knowledge from over 250 years of experience in cementing and condense their knowledge into this book. Real-life successful and unsuccessful case studies are included to explain lessons learned about the technologies used today. Other topics include job simulation, displacement efficiency, and hydraulics. A practical guide for cementing engineer, Applied Well Cementing Engineering, gives a critical reference for better job execution. Provides a practical guide and industry best practices for both new and seasoned engineers Independent chapters enable the readers to quickly access specific subjects Gain a complete framework of a cementing job with a detailed road map from casing equipment to plug and abandonment

This book covers the major physical and mechanical processes that unfold during cementing and subsequent well service, and which can affect the well integrity. Focusing on the underlying physics, it concisely presents the central concepts of well cementing. The authors discuss the displacement of different fluids in the annulus, the mechanical stability of cement subject to varying downhole temperature, pressure and in-situ stresses, and the impact of defects on cement integrity under different mechanical and thermal loads over the course of the well’s lifetime. The book identifies knowledge gaps and unresolved issues, and proposes new directions for future research and development. The book is a valuable resource for practising engineers in the oil and gas industry, academic and industrial researchers involved in oil and gas engineering, and to graduate students within this same sector.

Written and edited by some of the most experienced and well-known drilling engineers in the world and compiled under the auspices of the IADC Technical Publications Committee, this volume contains techniques and developments on well cementing never before gathered in one place, including an overview of the basic theory of well cementing, best practices and real-world applications, calculations and problem-solving exercises. Perfect for the engineer in the field or the student, there has never been such a comprehensive and in-depth treatment of well cementing published. Historically available only through experience or industry short courses, the information contained in this handbook is a valuable tool for the engineer and, for the first time, is readily convenient in this easily-accessible format.

Practical approach covering the chemistry, processes, and modeling in the field of cementing engineering Oil and Gas Well Cementing for Engineers brings together traditional technologies and new advancements in well cementing in a reader-friendly way, free of excessive technical information and data while still covering all the major aspects of cementing operations. The text covers theoretical and practical background related to nanocolloids. Laboratory evaluations of cement slurries are described to aid relevant specialists. Written by highly qualified authors with both theoretical knowledge and field operation experience in the field of cementing engineering, Oil and Gas Well Cementing for Engineers includes information on: Main properties of nanocolloids crucial for the practical application in petroleum engineering, such as stability, rheological behavior, and wettability Reservoir conditions necessary for nanocolloids formation and nano-gas emulsion hydrodynamics at reservoir condition Mechanism of nanoscale dispersion phase impact on physical properties of conventional substances utilized in upstream processes Impact of nanoparticles on conventional displacement agents and enhanced flow behavior of nanogels New perspective materials for petroleum engineering, such as metal string complexes due to extra metal ions and paddlewheel geometry Oil and Gas Well Cementing for Engineers covers all the major aspects of cementing operations and is therefore highly suitable as a student primer. Field specialists can make use of the practical side of the book which contains the necessary calculations required on site.

The blowout of the Macondo well on April 20, 2010, led to enormous consequences for the individuals involved in the drilling operations, and for their families. Eleven workers on the Deepwater Horizon drilling rig lost their lives and 16 others were seriously injured. There were also enormous consequences for the companies involved in the drilling operations, to the Gulf of Mexico environment, and to the economy of the region and beyond. The flow continued for nearly 3 months before the well could be completely killed, during which time, nearly 5 million barrels of oil spilled into the gulf. Macondo Well-Deepwater Horizon Blowout examines the causes of the blowout and provides a series of recommendations, for both the oil and gas industry and government regulators, intended to reduce the likelihood and impact of any future losses of well control during offshore drilling. According to this report, companies involved in offshore drilling should take a "system safety" approach to anticipating and managing possible dangers at every level of operation-from ensuring the integrity of wells to designing blowout preventers that function under all foreseeable conditions-in order to reduce the risk of another accident as catastrophic as the Deepwater Horizon explosion and oil spill. In addition, an enhanced regulatory approach should combine strong industry safety goals with mandatory oversight at critical points during drilling operations. Macondo Well-Deepwater Horizon Blowout discusses ultimate responsibility and accountability for well integrity and safety of offshore equipment, formal system safety education and training of personnel engaged in offshore drilling, and guidelines that should be established so that well designs incorporate protection against the various credible risks associated with the drilling and abandonment process. This book will be of interest to professionals in the oil and gas industry, government decision makers, environmental advocacy groups, and others who seek an understanding of the processes involved in order to ensure safety in undertakings of this nature.
